A slow-moving brush fire that may have erupted in a makeshift encampment used by transients blackened about a quarter-acre in an overgrown ravine near Sweetwater Reservoir on Monday.
The blaze, which caused no structural damage or injuries, began spreading shortly before 3:30 a.m. off in Spring Valley, according to Cal Fire.
It took about 25 ground personnel roughly 90 minutes to get the flames contained, said Kendal Bortisser, a fire captain with the state agency.
Investigators were looking into whether the activities of homeless people who frequent the area may have sparked the blaze, Bortisser said.
